The surgeon is asked if he has sufficient workspace to reach all places he need to operate. He is asked to grade this on a scale of 1 to 5, with 5 excellent and 1 impossible. If the grade is less than 3 and patient didn't get yet any NMB until that time a bolus of rocuronium 1 mg/kg IBW is given. The NMB will be kept in these patients at train of four (TOF) = 0 and PTC < 4 until release of the pneumoperitoneum.
